IMPRDVEMBNT IN GAS HEATBRS AND PETROLEUM STOVES.

To ALL WHOM IT MAY conocen! t Be it known that I, ALONZO T. BOON, of thecity 'of Galesburg, in the county of Knox', and State of Illinois, haveinvented a new and useful Improvement in Vapor Stoves for BurningPetroleum; and I do hereby declare that the following is a full, clear,and exact description of the construction and operation of the suine,reference.

being had to the accompanying drawings, making apart of thisspecification, 'in which- Figure 1 is a topview of my improved vaporstove.

Figure l2, a vertical sectionof the same, as indicated by the line :1: yin iig. 1.

Like letters in both figures ofthe drawingsv indicate like 'parts.

My invention-has reference to vapor stoves fdr burning coal oil,naphtha, or benzine, (or the ordinary gas may be used,) and is designedfor use in warm weather, or where it is not desired to heat the room.

l have a cylindrical stove, A, `supported on-suitableleg-s, vand having.a'pcrtion of the bottom, of a funnel shape, a, constructed up inwardlytherefrom. Within the stove, and bolted properly tothe funnel-shapedbot- -tom thereof, is a heatu-eonductoml, of a. cylindrical. ogee form,and made sufficiently smaller: than the outer cylinder as to have anairfchambemb, intervene between the two. The outer cylinder is providedwith a sui-tf able number of perforations, c, for the admission ofcoldair to the chamber1 Elevated and supported by a tube, C', isa reservoir,D, in which hydrocarbon liquids are placed. Theptube C is connected witha horizontal one, C, by an air and gas-tightjo'int', d, a'twhich pointis a temper-screw, c, for regulating the dow of the liquid into thehorizontal tube. The horizontal-tubeprojects downward at'right angles,and is curved through the side of the funnel-shaped bottom, the endterminating at the mouth of the funnel. A cap or burner,f, is screwed.on to the end, havingl a small hole through the centre of it to permitthe gas that maybe generated to escape.

The horizontal tube is made to pass through a solid heater or generator,E, or it may be made to pass over the same and then secured to it. Theheateris of a circular shape, and provided with a cone, g, over theburner, and having a concave surface formcd'from the sloping 'sides ofthe coneto the periphery ofthe heater. V I

As the liquids would perhaps Vdow too rapidly in the tubes from thereservoir to the heater, and thus endanger the person .volatilizing theliquid, a bundle of short, fine wire, held together by bands, isintroduced in the tube near the heater, the effect of which will be toretard thc'lo'w of the liquid suiiiciently just before reaehin'gtheheater to prevent this. This bundle of wirc is representedv vby F, andis not 4shown in the .tube as above described, not deeming it necessary,as it will beobvious its connection therewith will be readilyunderstood. i

'.lhc point of my invention is this: The effect 'of the funnel-shapedbottom of the stove willbe to concentrate a strong current'cf air at agiven point (its mouth) arounfd the bnrner,'that'is, when the liquid hasbecome suieiently volatilised by the action of heat independentlyapplied to the heater', other than that produced from the.liquid,iwhichvolatile or gaseous mattermixingl with the current of air thus obtainedwill create a steady' and powerful tlanie, and consequently a powerfulheat upon the heater, and which, if the under-surface .of the .heaterwas entirely a plain one, the heat would probably affect the tube overor in vit to suchan extent as to cause an explosion of the fluidtherein; therefore to obviate this itwill be found that the point 'ofthe cone will deflect the fla-me radially therefrom, and bythe concavesurface ofthe heater it will be caused to expand itselfsomewhatobliquely downwards from the edge of the heater on to and within theconcave par-t of the agee cylinder; It will now be observed from theswelling in orcontractiou of the upper part of thecylinder to a convexform, the heat ascending will become concentrated at this poi-nt,l andhence will-be expanded fully from the diverging sides ofthe cylinderupon the cooking utensil that may be placed above on the stove.`

Operation: The reservoir is filled with naphtha or benzine; a-'sponge,aliixed to a piece of wire, saturated in alcohol and set on tire, isthen applied 'to the mouth. of the funnel, sc thatthe-heat will reachthe heateri After holding it la moment, or until the heater becomessufficiently hot, the temper-screw is turned slightly, so as to allowthe fluid to iiow,and when it reaches the wireit will -permeate slowlythrough it and thus gradually come in contact with the heating surfaceofthev tube, at which point its reduction to a gaseousistate will beindicated by its ignition at the burner from the Contact of the flame ofthe sponge therewith. The spongeris then withdrawn, and theburner'continues to Supply itself automatically'. I

-By detaching the horizontal tube, or that part of it extending to themouth ofthe funnel, and applying the' ordinary gas from aburner standhaving a'gutta-percha tube attached thereto and connecting with aceiling or Patent, isi 4 v TheV bundle of short, fine wire F, incombination with the horizontal tube C, substantially in the manner andfor the purpose as herein set forth.

h ik wall burner, the heater may be heated, and. the cone so' affect thefia-nre :is to cause aogumnguhication of the heat therefromto the ogeecylinder in the-manner hereinv described.

It will be found that the perforations will admit the necessarynmountuof coid'air to the Vchamber to prevent the outer` cylinder frombecoming too hot, 'so vthat no discomfort will bei'occasionedin the useofthe stove in warm weather.

Having thus. fully described my invention, what I claim therein: as new,and desire to secure by Letters l The-,solid heater E, as'constructed,andprovided with a. cone, g, in 'eombination'with'thehorizontal tube O,

substantially in the manner and' for the purpose as herein set forth. v

The ogeo cylinder B, in combination with. the funnel-shaped bottorma ofthe stove, substantially in the manner anni for the purpose as hereinset forth.'
